Mine was only a proof of concept, so I'm glad someone at NASA made a more refined version. Their version apparently fuses more streams of telemetry to represent the true rover position at very small intervals, while mine was limited to only the Navcam image locations that were interpolated.

Cut of the original video with the #3IATLAS cameo. The video is reversed, I find it easier to find it with it going from right to left. Its path starts below the saturated region on the middle right and goes in a slight diagonal towards the left.

Hey #planetSci friends, the end of the year is nearing. Does anyone want to help me put together an Image of the Year Bracket? If you want to propose your favourite planetary science image of 2025, place it below with a link to the source and when it was published.

Bracket for "BSky Planetary Science Image of 2025" contest, featuring small icon of 16 boxes with question marks grouped into four quarter-finals. There are finalist placeholders against a lunar surface backdrop.

@wierzchos.bsky.social qué sorpresa encontrarte referido en un paper sobre coatings en Marte, se me había olvidado a lo que se dedicaba tu padre 😉 onlinelibrary.wiley.com/doi/10.1111/... agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Microbial colonization of Ca‐sulfate crusts in the hyperarid core of the Atacama Desert: implications for the search for life on Mars

The scarcity of liquid water in the hyperarid core of the Atacama Desert makes this region one of the most challenging environments for life on Earth. The low numbers of microbial cells in the soils ...

Yesterday Curiosity took pix of jagged peaks in the distance with its ChemCam. I stitched them together, did some work on them, and... just look at that view... I've been doing this since Sojourner landed & this is one of my fave images ever... Credits: NASA/JPL-Caltech/LANL/S Atkinson

I've been asked a few times over the last few days what I think the chances are that the "leopard spots and poppy seeds" on Mars will turn out to be actual evidence of life. People are naturally skeptical given the history of possible signs of life on other planets. Strap in: long thread ahead...

After poking around and finding the base of the flow, the story became much richer: the basalt had flowed over some eolian dunes which sourced the water for the hydrothermal system. The sand might have accumulated as obstacle dunes around a bedrock hill, then buried by the flow in a valley. (2/2)

Outcrop photo of Miocene eolian dune deposits overlain by vesicular basalt. The dune deposits are light orange-brown and characterized by wind ripple/translatent (pin-stripe) laminations, and the basalt is very dark reddish brown. the contact is very sharp. There is ddesert vegetation, including saguaro cacti visible in the background.Outcrop photo of Miocene eolian dune deposits overlain by vesicular basalt.

The IAU announced official names for Donaldjohanson's surface & shape features 2 weeks ago, but nobody has mentioned the news. They're all named after archeological sites and hominin fossils, which is fun and awesome haha (Afar Lobus = small lobe, Olduvai Lobus = big lobe, Windover Collum = neck)

Lucy image of asteroid Donaldjohanson, with features labeled with their formal names approved by the IAUA screenshot of the IAU's announcement of 11 new names for Donaldjohanson's surface+shape features. The text reads: 11 Names Approved for (52246) Donaldjohanson: Afar Lobus, Olduvai Lobus, Hadar Regio, Minatogawa Regio, Luzia Dorsum, Boxgrove Saxum, Kennewick Saxum, Cashel Saxum, Mungo, Narmada, and Windover Collum 08/27/2025 The IAU Working Group for Planetary System Nomenclature has approved the names Afar Lobus, Olduvai Lobus, Hadar Regio, Minatogawa Regio, Luzia Dorsum, Boxgrove Saxum, Mungo, Narmada, Kennewick Saxum, Cashel Saxum, and Windover Collum for eleven features on the asteroid (52246) Donaldjohanson. For more information, please see the Donaldjohanson nomenclature map in the Gazetteer of Planetary Nomenclature.

If you liked the quoted cloudy panorama by @stim3on.bsky.social, there's a relevant current #Zooniverse project: www.zooniverse.org/projects/mat... with #MavenMission UV mosaics. Not a simple task, but a good one to grasp how much activity there is in the Mars atmosphere. #PlanetaryScience

Sample mosaic from the Zooniverse project, the Mars disk built of traverse slices with mapped UV colors. Multiple cloud formations are seen over the Tharsis region, with the dormant volcanoes showing as dark spots.

Just a few hours ago, the Perseverance rover captured this afternoon view of some wispy clouds above the Nili Planum region on Mars. flic.kr/p/2rkCrHu Credit: NASA/JPL-Caltech/Simeon Schmauß

wide format panoramic image of a reddish landscape with small hills that fade into the haze towards the horizon. The sun is just above the field of view of the camera, but it's glare shines through some wispy clouds in the sky.
